⚠️ Important Installation & Maintenance
Where to install: Install on the breather hose connecting the cylinder head to the air filter box. If you're not familiar with motorcycle mechanics, we recommend professional installation!
Direction Matters: The arrow on the valve body must point in the direction of the airflow.
Routine Maintenance: Clean the valve every 2,000 km. We recommend using WD-40 for cleaning—it's gentler on the internal components.
Oil is Normal: It is completely normal to find a small amount of oil inside the valve when removing it for maintenance.
